У меня анимация не циклична и выходит вот такая ошибка:
MissingComponentException: There is no ‘Animation’ attached to the «Руки 1» game object, but a script is trying to access it.
You probably need to add a Animation to the game object «Руки 1». Or your script needs to check if the component is attached before using it.
